Codes run the world, and cryptography inhabits our daily lives from entertainment, shopping online, ATMs, and even doing business. Cryptography is the science of secret communication where objects are used to transfer information through insecure channels without understanding the third party. With the technological changes, cyber-attackers have led to the need for secret codes to safeguard sensitive data. For example, everyone nowadays uses ATMs to withdraw money from the bank and do other transactions without visiting a bank and queuing. A bank authorizes each ATM transaction through a secure communication network that relies on encoding data to reach the recipient.
